We won't know until you let us see the grid.
4 x 4 = 16 For any grid n by n, the number of squares is equal to n2 (or n x n)
x=x
You just have to follow the rule of quadratic functions.Example y = mx+b is the rule for linear functions.ax^2+bx+c is the rule of quadratic equation.
A non-linear equation is any equation which includes variables with a degree other than one. Therefore, any equation involving x2, x3, x4, .... would be non-linear.For example: y= 3x+2 is linear,...
